Adding buttons to the ribbon with custom functions

[ilyachaban]

I've been using VB API for a couple of weeks now and now i want to add a button to the ribbon. But I can't even start an application in CREO. 
My code looks like this:

Imports pfcls

Module Module1
    Public asynconn As New CCpfcAsyncConnection
    Public conn As IpfcAsyncConnection
    Public session As IpfcBaseSession
    Sub Main()
        user_initialize()

        user_terminate()
    End Sub
    Sub user_initialize()
        conn = asynconn.Connect("", "", ".", 1)
        session = conn.Session

    End Sub
    Sub user_terminate()
        conn.Disconnect(5)
    End Sub

End Module

My protk.dat file:

NAME test
EXEC_FILE D:\Users\Creo_7\Test_Button.dll
TEXT_DIR D:\Users\Creo_7
STARTUP dll
delay_start FALSE
allow_stop TRUE
REVISION 2001
END

 config.pro:

protkdat D:\Users\Creo_7\protk.dat

What is a minimum requirements for creo VB application to run inside of CREO and how than can I add button on the ribbon?

VladimirN, thank you for those materials bu the didn't help me. 
Is there anything like this for VB API. I've found it in user guide for TOOLKIT.

I'm able to start and use scripts that I have for now by running them in visual studio but I can't register application in creo.

Some solutions for this error:

• "A Creo Parametric Object TOOLKIT C++ application can be started successfully when built in Debug mode, but fails to start when built in Release mode": https://www.ptc.com/en/support/article/CS347228
• "Error: Foreign program "XXX" failed to initialize: code 1 when launching Creo Parametric": https://www.ptc.com/en/support/article/CS220487

All those articles are for TOOLKIT but I'm using VB API.
